HORSESHOE.

SPECIFICATION foiming part of Letters Patent No. 374,911, dated December 13, 1887.

Application filed January 24, 1887. Serial No. 225,281.

To aZZ whom it may concern.-

Be it known that I, ALFRED L. SrEvENs, a citizen of the United States, residing at Darien, in the county of Fairtield and State of Connecticut, have invented certain new and useful Improvements in Horseshoes, (said invention having been patented in Canada November 12, 1886, No. 25,347;) and Ido hereby declare the following to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the class of horseshoes in which the body ofthe shoe is formed in a single piece, and detachable and interchangeable calks are made separately therefrom and adapted to be attached thereto at any time and without the necessity for skilled labor.

The objects of my present invention are to simplify the construction of the shoe, to lessen the cost of manufacture, and at the same time to greatly improve the operation of the shoe as a whole, the essential requirements being that the parts shall be joined together in such a manner that all danger of the parts not fit ting together shall be avoided and the time and trouble required in detaching a set of calks and attaching a new set shall be reduced to the minimum. With these ends in view I have devised the simple and novel construction, of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to indicate the several parts of the shoe.

Figure 1 is a bottom plan view of the shoe with the calks in place, two styles of sharpened heel-calks being shown; Fig. 2, asection through the heel of the shoe and heel calk, the attaching-pin being shown in elevation; Fig. 3, a section through the toe of the shoe, showing the lug uporr the calk and the attaching-pin in elevation; and Fig. 4 is an end elevation of the heel of the shoe with the calk detached.

1 denotes the body of the shoe; 2, grooves for the nail-heads; 3, the nail-holes; 4, the toecalks, and 5 the heel-calks. The calks are all provided with bases 6, which are fiat upon their under sides and are made straight on the sides which come in contact with the body of No model.) Patented in Canada November 1-2, 1886. No.25.3-17.

the shoe. Upon the under sides of the bases are round lugs 7, which are preferably made slightly tapering, as shown, and are provided with holes 8, also made tapering, which pass through them horizontally in the longitudinal direction'of the shoe. At the toe of the shoe is a recess or depression, 9, which is provided with a straight wall or shoulder, 10, corresponding with the back face of the base of the toe-calk.

17 denotes holes from the recess through the shoe from bottom to top. These holes are made round and correspond with lugs 7,which they receive.

11 denotes a hole through the toe of the shoe from front to back. This hole corresponds with hole 8 through the lug, the taper being uniform therewith.

12 denotes recesses or depressions at the heel of the shoe, each of which has a straight wall or shoulder, 13, which corresponds with the rear face of the base of the heel-calk.

14 denotes holes at the heel of the shoe, which extend inward from the back and into slots 15 in the body of the shoe a short distance forward of the heel-calks. Holes let, like holes 11, correspond with holesSthrough the lugs, the taper thereof corresponding. Both heel and toe calks are held in place by pins 16, which are tapered to correspond with the holes through the shoe and the lugs. The pins at the toe are driven in from the front and pass through the lug and entirely through the body of the shoe,so that they may be readily driven out from the inner side. The pins at the heel of the shoe are driven in from the back and pass through the lug and into slots 15. They may be readily driven out, when it is desired to remove a calk, by using a punch in the slots. As already stated, the results secured by my present construction arestrength, durability, ease of management, and cheapness of construction.

The shape of the body of the shoeissoplain that it may be forged'without diificulty. The

calks likewise are forged. The lugs upon the calks and the corresponding holes therefor in the body of the shoe are made round, as it is easiest to make them so, and they work better in practice. The engagement of the straight sides of the bases of the calks with the straight IOC walls or shoulders in the body of the shoe gives the strongest and at the same time the simplest possible connection between them. In practice they are found to stand the hardest kind of service, and to wear out without becoming loose.

I do not claim, broadly, a horseshoe having calks the'lugs of which are secured in apertures in the shoe by transverse pins, as such construction is not new with me.

Having thus described my invention, I claim- A horseshoe having a depression or recess bounded by a shoulder, as described, a tapering aperture, and a second aperture intersecting or passing transversely through the first aperture, a calk abutting at its base against said shoulder, a tapering lug on the calk entering and fitting said first aperture and havinga transverse perforation, and a tapering pin or key adapted to be driven through said transverse aperture and perforation to draw the lug into its seat, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED L. STEVENS.
